 DETAILED DESCRIPTION
FIGS. 1-5 show a lens module assembling device 100 according to an exemplary embodiment. The lens module assembling device 100 includes a platform 10, a deformable support member 20, a deformable limiting unit 30, and a gas blowing device 110.
The platform 10 is substantially cuboid. The material of the platform 10 is metal. The platform 10 includes a first surface 12 and a second surface 14 opposite to the first surface 12. The first surface 12 defines a receiving recess 16 configured for receiving the deformable support member 20. An inner diameter of the groove 16 is slightly greater than a diameter of a lens barrel 50. This ensures that the lens barrel 50 is not inclined during an assembling process. The platform 10 includes a bottom surface 160 in the receiving recess 16. The platform 10 also includes a number of through holes 180 extending through the bottom surface 160. The through holes 180 are uniformly distributed on the bottom surface 160 and through the bottom surface 160 and the second surface 14.
The deformable support member 20 is positioned in the receiving recess 16 on the bottom surface 160 in such a way that the through holes 180 are exposed and the through holes 180 surround the support member 20. The deformable support member 20 supports the lens barrel 50. The height of the deformable support member 20 is less than the depth of the recess 16 and this ensures that a portion of the lens barrel 50 is received in the recess 16. The deformable support member 20 is substantially a cylinder. The material of the deformable support member 20 is sponge, rubber, soft wood or foam plastic.
The deformable limiting unit 30 is arranged on the first surface 12. The deformable limiting unit 30 includes a limiting hole 34 configured for extension a portion of a lens therethrough, and the limiting unit 30 configured for blocking the lens module from moving out of the recess 16. The lens barrel 50 is arranged on the deformable support member 20 during the assembling process. In this embodiment, the limiting unit 30 includes two limiting pieces 32, and the two limiting pieces 32 cooperatively form the limiting hole 34. Each of the limiting pieces 32 defines a hole 36 and includes a semicircle surface for conforming to an outer wall of the lens barrel 50 of the lens module. The limiting piece 32 is made from sponge, rubber, wood or foam plastic.
The lens module assembling device 100 also includes a first screw 121 and a second screw 123, and the first surface 12 defines a first screw hole 120 and a second screw hole 122. The first screw hole 120 and the second screw hole 122 are located on opposite sides of the recess 16. The first screw 121 penetrates the hole 36 and is engaged in the first screw hole 120 to fix the one limiting piece 32 on the first surface 12. The second screw 123 penetrates the hole 36 and is engaged with the second screw hole 122 to fix the other limiting piece 32 on the first surface 12. In the this embodiment, the lens module assembling device 100 also includes two spacers 38, each of the spacers 38 is sandwiched between the first surface 12 and the limiting piece 32 to adjust the distance between the limiting hole 34 and the first surface 12.
The gas blowing device 110 is arranged below the second surface 14 of the platform 10, and configured for blowing gas to the lens barrel 50 through the through holes 180. The gas blowing device 110 includes a control system (not shown), and pressure parameter of air flow and duration parameter are predetermined in the control system.
An assembling method using the lens module assembling device 100 includes the following steps.
Step 1: The lens module assembling device 100 is provided. The limiting piece 32 is not mounted.
Step 2: The lens barrel 50 and two optical elements 60 are provided. In this embodiment, the two optical elements 60 are respectively an optical lens and a spacer ring. The lens barrel 50 includes a projection 52 along the peripheral of the lens barrel 50. First, the lens barrel 50 is placed on the flexible supporting part 20. In the embodiment, an end of the lens barrel 50 with a light aperture is placed on the flexible supporting part 20. Second, the lens barrel 50 is limited by the two limiting pieces 32 with the limiting hole 34. In the embodiment, the spacer 38 is placed on the first surface 12 and the limiting piece 32 is located above the spacer 38. The first screw 121 penetrates the hole 36, the spacer 38 and the first screw hole 120 and then fastens the one limiting piece 32 on the first surface 12. The second screw 123 penetrates the spacer 38, the other limiting piece 32 and the second screw hole 122 and fastens the other limiting piece 32 on the first surface 12.
Step 3: The gas blowing device 110 is opened to apply stable air flow 111. The air flow 111 can arrive at the bottom end of the lens barrel 50 via the through holes 180. A suction nozzle (not shown) is applied to pick up the optical elements 60 and assembles them into the lens barrel 50, and then a lens module is obtained. In this embodiment, the buoyant force applied by the gas blowing device 110 is greater than the pressure force applied by the suction nozzle and the gravity of the lens module. In this embodiment, the lens barrel 50 is not in contact with the flexible supporting part 20 during the assembling process, and damage to the lens module is avoided.
Step 4: the gas blowing device 110 is shut down, and the lens module is moved away.
